ABSTRACT
Objective: To study the serum interleukin-37 (IL-37) level changes in patients with acute coronary syndrome (ACS) and to explore the relationship between IL-37 and coronary atherosclerotic plaque. Methods: Our research included 3 groups. ACS group, n=60, SAP (stable angina pectoris) group, n=30 and Control group, the subjects with normal coronary artery, n=15. The peripheral serum levels of IL-37 were examined by ELISA and the differences were compared among different groups. Results: ① The serum levels of IL-37 at admission were as ACS group SAP group>Control group, P77ug/L. Conclusion: The serum IL-37 might be involved in the inlfammatory process in ACS patients, it could be expected as an index for ACS monitor and evaluation in clinical practice.
ABSTRACT
Objective To evaluate the effects of two different dosage of rosuvastatin on endothelial dysfunction in diabetic rats. Methods The 24 diabetic rats were randomly divided into three groups (n=8,each): diabetic control group, 20 mg rosuvastatin daily (RV 20 mg group) and 10mg rosuvastatin daily for 8 weeks (RV 10 mg group) and normal control group (SD group). The levels of blood glucose, lipid, nitric oxide(NO) and endothelin-1 (ET-1) were measured before and 8 weeks after treatment. Results The levels of blood glucose were higher in all diabetic rats groups than in SD group before experiment (P＜0. 01). Compared with diabetic rats control group, blood glucose was slightly lower in RV 10 mg group and RV 20 mg group at 8 weeks (P＞0. 05). The plasma NO level was significantly lower in diabetic rats control group than in SD group (P＜0. 05).After 8 weeks, plasma NO levels were significantly higher in RV 20 mg and RV 10 mg groups than in diabetic rats control group (P＜0. 01 or P＜0. 05). The plasma levels of ET-1 was significantly higher in diabetic rats control group than in SD group (P＜0. 01). After 8 weeks, plasma ET-1 levels were significantly lower in RV 20 mg and RV 10 mg group than in diabetic rats control group (P＜0. 01).Meanwhile, the plasma lipids were lower in RV 20 mg and RV 10 mg group than in diabetic control group (P＜0. 05 or P＜0. 01). Conclusions Rosuvastatin can adjust blood lipids and significantly improve endothelial function in diabetic rats by increasing plasma NO level and decreasing plasma ET-1 level.
